Solicitation I contact you on behalf of your tender requirement for a cylindrical grinding machine for a weight capacity of 30 000 lbs and 7 meters grinding length. I would need drawings of the part in order to adjust the quotation exactly according to your requirements. I would appreciate more requirements for the machine -swing diameter, etc.

The information you required is in paragraph 3.2.2.1 and 1.1.

Solicitation 1. Minimum swing over Table..... 24” (610 mm).==> Does this refer to the diameter or the radius?

2. Minimum weight between centers without steadies...... 10,000 lbs. (9071 kg)==> The conversion seems incorrect, which one prevails? 10,000 lbs would be

1. Diameter

2. 10,000 lbs. 4,536 kg.

3. (This machine needs to hold 30K LBS with steady rest) its contractor’s prerogative.

7/15/21 7/19/21 roughly 4,536 kg, while 9,071 kg would convert to 20,000lbs. Should we be quoting a machine with 10,000lbs capacity between centers or 20,000?

3. Minimum weight between headstock and steady… 30.000lbs 13607kg.==> Considering that we will need to machine the areas where the steady holds the parts, should we quote a machine with 30,000lbs capacity between centers?

Solicitation -Does the machine go outside?

-Unloaded with a crane? Or inside somewhere where we have to unload with a crane then roll it into a building?

-What building is this? If it goes inside, how far does it go?

-What building does this machine go into?

-Where within the building will it go?

WVA does not have storage locations at this time.

Yes, a crane will be needed or a large versa lift.

The machine is going in building 35 A bay section 20 once out of storage. There are cranes available in the building, but WVA doesn’t guarantee the cranes will be available. There is an overhead door close to the final location of the grinder.

There are a couple different ways to access the locations, it is up to the rigging company.
